Alfred Scott's first motorcycle was developed from his own twin-cylinder engine design which he hand built and fitted to the steering head of a bicycle. These engines were used to power equipment such as lathes and light machinery and Scott had been involved in the manufacture of 'Premier' pedal cycles. designed a
fully triangulated frame, rotary induction valves, and used unit construction for his motorcycle engine. Scott started making boat engines in 1900. He patented his first engine in 1904 (Patent GB 3367 of 1904) He formed
The Scott Motorcycle Company in 1908. The motorcycles produced there were very successful in competitions, winning the fastest laps at the
Isle of Man TT (Tourist Trophy race) from 1911 to 1914, with outright wins in 1912 and 1913. Scott's two-stroke motors were deemed to be "too efficient" for racing against four-stroke motorcycles of the same capacity, so their cubic capacity was multiplied by 1.32 for competitive purposes. Alfred Scott left the company in 1915 to form the Scott Autocar Company in nearby Bradford. By 1916 e had developed a hybrid between a motorcycle-and-sidecar combination and a compact car, which he called the
Sociable. It was based on the machine gun carriers which the Scott Motorcycle Company were making at the time, but had its single front wheel moved to the offside in line with the driven rear wheel. The wooden bodywork was mounted on a tubular, triangular frame and the engine was Scott's own design, a 578 cc water-cooled, two-cylinder, two-stroke engine. The idea was not a success, production start had to wait until after the war, and ended in 1925. ==See also==
